Because transparent plastics require high light transmittance, the surface quality of the plastic products must be strictly controlled. Defects such as blemishes, pores, whitening, haze, black spots, discoloration, and poor gloss are unacceptable. Therefore, the entire injection molding process requires careful attention and stringent, even specialized, requirements for raw materials, equipment, molds, and even product

How significant is the impact of wall thickness on the quality of plastic parts during processing? The wall thickness of plastic parts has a significant impact on their quality. When the wall thickness is too thin, flow resistance increases, making it difficult to fully fill the mold cavity—particularly for large or complex plastic parts. The

Dents are caused by local internal shrinkage after the gate is sealed or due to insufficient injection. Depression or micro-depression on the surface of injection molded products is an old problem in the injection molding process. Dents are generally caused by the increase in the wall thickness of the plastic product, which causes a local

Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. The toughness of the mold mainly depends

Injection molding: also known as injection molding, its principle is to add granular or powdered raw materials into the hopper of the injection machine. The raw materials are heated and melted into a flowing state. Under the push of the screw or piston of the injection machine, they enter the mold cavity through the nozzle
